Customize how many days of tasks are shown (instead of 7 days)

dr.vermeulen says:

I have some important tasks that only have their deadline 2 weeks in the future. I added them to the list, to be reminded regularly of these big tasks, so I don't postpone working on them for too long.
The RTM gadget is so programmed to only start doing what it's intended to do something like a week before the deadline. When it'll probably be too late to complete them in time. (I mean, it's intended to remind me of still waiting tasks, right?)
